29the Effect of Nano-Composites on the Mechanic and Morphological Characteristics of NBR/PA6 Blends

Abstract:

The present article dealt with studying physical and mechanical properties of binary blend of NBR/PA6. First, samples of NBR/PA6 blends were prepared as control samples then; the effect of Nano-particles on them was studied. The samples mixed with the weight percentages of PA6 (20, 40, and 50) and (2, 4, and 6) percentages of Nano-particles in an internal mixer and experimented after pressing and molding. XRD results showed that increasing Nano-clay particles causes the particles diffusion, the distance between them and the resistance of the samples to be increased, which can be seen through the mechanical results. DSC results showed that increasing NBR and 20 A Cloisite causes crystallization percentage to be decreased because of decreasing polymer and increasing rubber with lower heat resistance. Increasing Nano-clay has no effect on this property. Increasing Nano causes hardness resistance to be compressed and increased and increasing NBR causes this resistance to be decreased because of its elasticity. Furthermore, increasing Nano-particles in impact test can result in decreasing resistance. In tensile samples, increasing Nano-clay with the elasticity of PA6 results in increasing resistance. The objective of this article is to study the effect of increasing Nano-particles of clay on morphology and mechanical properties including tensile strength, Young’s modulus and impact resistance of binary blends based on NBR/PA6.
